| 1. A separation process comprising:
substantially continuously contacting an ion exchange medium which is ion exchanged with silver and/or copper ions with a
feed stream comprising E and Z isomers of at least one alkene alcohol derivative, and, optionally, one or more contaminants
or impurities;
removing at least one product stream having a higher isomeric purity of the E or Z isomer of at least one alkene alcohol derivative,
relative to the isomeric purity of the E or Z isomer of the alkene alcohol derivative in the feed stream.
